[原文]Buffer overflow in IBM Informix Dynamic Server (IDS) 9.40.TC7, 9.40.TC8, 10.00.TC4, and 10.00.TC5, when running on Windows, allows remote attackers to execute arbitrary code via a long username, which causes an overflow in vsprintf when displaying in the resulting error message. NOTE: this issue is due to an incomplete fix for CVE-2006-3853.

NGSSoftware Insight Security Research Advisory

Name: Error logging buffer overflow in Informix
Systems Affected: Informix 9.40.xC7 and xC8, 10.00.xC3 and xC4
Severity: Critical
Vendor URL: http://www.ibm.com/
Author: David Litchfield [ davidl@ngssoftware.com ]
Date of Public Advisory: 2nd August 2006
Advisory number: #NISR02082006B
CVEID: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3854
Advisory URL: http://www.ngssoftware.com/research/

Description
***********
Informix Dynamic Server is a database developed by IBM. When IBM released a 
patch for the overly long username buffer overflow (CVE-2006-3853) it was 
discovered that the patch introduced a new buffer overflow vulnerability.


Details
*******
If the username is longer than 32 bytes an error is logged. A message ("%s : 
username is longer than usersize(32).") is logged with a call to 
_mt_logprintf(). _mt_logprintf() creates a 960 byte buffer on the stack and 
then passes this as argument for the destination in a call to vsprintf(). 
Thus if the username is longer than 960 bytes it is possible to overflow the 
buffer, overwriting the saved return address, gaining control of the 
process' path of execution.


Fix Information
***************
IBM was alerted to this flaw on the 21st July 2006; a fix has now been made 
available - both 9.40.xC9 and 10.00.xC5 fix this issue.
